What this MCCB delivers on the line
The Siemens SENTRON 3VM1180-4ED42-0AA0 is a 4-pole molded case circuit breaker rated 80 A continuous at 40 °C, with a TM210 thermal-magnetic release for line protection. Its interrupting capacity hits 121 kA at 240 V AC, 76 kA at 415 V, 53 kA at 440 V, and 12 kA at 500 V — numbers that define the available fault current it can safely clear at the point of installation. The 800 V rated insulation voltage (Ui) and 690 V max AC operating voltage cover most industrial distribution panels. IP40 on the front means it's protected against solid objects over 1 mm but not sealed against moisture; mount it inside a suitable enclosure. Current rating holds flat at 80 A from 40 °C through 50 °C, then derates to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. If your panel ambient runs above 50 °C, factor that derating into the load schedule — the breaker won't trip early, but continuous current capability drops.
Panel fit and mounting
Dimensions are 101.6 mm wide, 130 mm high, 70 mm deep — a 4-pole MCCB footprint that fits standard Siemens SENTRON panel cutouts and busbar systems.
